James Clark was a motorcycle enthusiast. He had a life-long passion for riding, and began wrenching on his own and friend's bikes in his parents garage early on. He spent some time working for a Harley-Davidson® dealership before opening his own motorcycle repair shop, Chino's, in Fremont, California. Being dissatisfied with the gaskets that he found available, James began to cultivate his own ideas for improved sealing technology. In 1977, James started the James Motorcycle Parts Company. Paying close attention to quality and fit, he quickly gained a reputation for producing superior gaskets and seals. Rocker gasket kit. Detailed Specifications: Used on: 1991 and up.
